general viewItís still cloudy and windy and cold. This weather is better for wheat than our soybean field. The crabgrass doesnít appear to be as green as it was earlier in the week, so the herbicide is working. Letís look closer.


general rowNow, that looks much better, as far as weeds go. By next week I donít think there will be any crabgrass left. There are some cracks in the soil down the rows. Can you see the cracks? That will be the seedlings trying to emerge. Weíll need to dig to see the seeds.


seedling undergroundWell, this seedling was less than an inch below the soil surface. Notice this seedlingís cotyledons are yellowish and the hypocotyl is white. Letís dig this one up to take a look at it.

 


seedling exposedThis should give you a better idea of what a soybean seedling looks like. Do you see what I mean about the crookneck stage? That crook will straighten out and the cotyledons will push through the soil crust. Letís look around some more.
seedling emergingTake a look at this. You can see one or two seedlings breaking through the soil surface. Soybean seedlings exert a considerable amount of force to push through the soil surface. Letís dig back the crust so we can see these two seedlings.
seedling emerging without crustWow! Look at all those seedlings about ready to emerge.  I guess we helped them out a little. Notice these seedlings are greener than the first seedling ... why do you think thatís the case? Well, I think these seedlings were getting some sunlight because the crack was rather big, while the first seedling was still underground and couldnít get any sunlight. The green color is, of course chlorophyll (we will tell you about chlorophyll later).
